Hi.

I’m using openvidu docker image on ubuntu 20.04 and I need to create a custom kurento filter to bluring faces so I’m following this tutorial:

[https://doc-kurento.readthedocs.io/en/stable/user/writing\_modules.html#writing-kurento-modules](https://doc-kurento.readthedocs.io/en/stable/user/writing_modules.html#writing-kurento-modules)

As indicated, it’s needed to install kurento-media-server-dev package (which include kurento-module-scaffold tool) but like I’m using ubuntu 20.04 I have to use the docker image kurento/kurento-media-server-dev.

I’ve inspected this image content and there isn’t any scaffold tool.

Please, could you tell me how I can use this tool in this situation or if there is some alternative?

Thanks in advance.

Regards.

Hi, the easiest would be to use the Kurento Docker image as a development environment; for that, you can start a container with a different entrypoint and a bind-mount to your development directory.

An example command would be like this. Let’s say that `work` is your work directory:

```nohighlight
cd ~/work

docker run --pull always --name kurento-work -ti \
    -v "$PWD":/work \
    --entrypoint /bin/bash \
    kurento/kurento-media-server-dev:latest

```

This will create a new container, named `kurento-work`, and mount your work directory into `/work` inside the container.

Now, _inside the container_, you can run `apt-get` and other commands, as normal:

```nohighlight
apt-get update ; apt-get install --yes kurento-media-server-dev

cd /work

kurento-module-scaffold [...]

```

Note that when you `exit` from this container, you can later re-access it again with

```nohighlight
docker start -ai kurento-work

```

and to delete the container when you no longer need it:

```nohighlight
docker container rm kurento-work

```

Great, I’ve achieved build the scaffold!

Thanks for your held.
